2 Claims. (Cl. 294-67) This invention relates to an improved carrier forcircular articles, such as large grinding wheel stones.

An object of the invention is to provide a carrier which enables a heavyarticle to be easily picked up, transported safely, and released, andalso functions as a jig for performing operations on the article, suchas mounting a grinding wheel stone on a hub.

A further object is to provide a carrier of simple construction whichovercomes the need for manually rolling large grinding wheel stones totransport them and for manually positioning them on hubs, thuseliminating hazards to workmen.

In accomplishing these and other objects of the invention, I haveprovided improved details of structure, a preferred form of which isshown in the accompanying drawings, in which:

Figure 1 is a side elevational view of an improved carrier constructedin accordance with my invention;

Figure 2 is an elevational view of the carrier taken at right angles toFigure 1;

Figure 3 is a fragmentary side elevational view similar to Figure 1 buton a larger scale; and

Figure 4 is a fragmentary elevational view similar to Figure 2 but on alarger scale.

My carrier includes an annular base plate which has diametricallyopposed integral ears 11 and arcuate flanges 12 welded to the ears andprojecting therefrom. U-shaped bars 13 are welded to the exteriors ofthe respective flanges 12. Bearing pins 14 are welded to the exteriorsof the respective flanges 12 and extend radially through the bars 13.The outer end portions of pins 14 contain diametric bores whose axes areinclined to the plane of the base plate 10, preferably at 45. Pins 15are permanently fitted into these bores with their end portionsprojecting from opposite sides of the bearing pins 14. Connectors 16 areremovably pivoted on pins 14 in the spaces between the outside of bars13 and the projecting pins 15. The connectors have keyhole slots 17which enable the connectors to be slipped over pins "15 when the slotsare aligned with the pins (Figure 4). The carrier includes a yoke 18 andchains 19 which are suspended from the yoke and joined at their lowerends to the connectors 16.

A pair of spaced blocks 20 are fixed between each bar 13 and flange 12.Diametrically opposed J-shaped keepers 21 are pivoted to the respectivepairs of blocks. The longer arm of each keeper extends through bothblocks 20 and carries a cotter pin 22 intermediate the two blocks and anut 23 at its end. A compression spring 24 encircles the longer arm ofeach keeper between the upper block 20 and the cotter pin 22 and thusurges the keeper toward the base plate. The shorter arm of each keepernormally bears against a plate 25 which spans the space between theflange 12 and bar 13.

In operation, the base plate 10 is placed against a circular article,such as a large grinding wheel stone, as shown in Figure 1. If thearticle is standing on edge, the base plate can be tilted about pins 14into a vertical "ice position for engagement with the article. Keepers21 are turned to position their shorter arms over the article and areheld in this position by springs 24. A crane hook can be engaged withthe yoke for transporting the carrier and article. Normally the baseplate remains in a vertical position when transporting an article.Flanges 12 and keepers 20 retain the article against accidental droppingwhen transported in this position. Nuts 23 limit outward movement of thekeepers and thus take the load oif the cotter pins 22. The crane canplace the article over a hub, and the base plate and article can easilybe turned about pins 14 to a horizontal position for attaching the hubin the usual manner. Since the base plate is annular and has a centralopening, it does not interfere with this operation. Thereafter thearticle can be carried wherever it is needed, and the carrier releasedtherefrom.

F-ro'm the foregoing description it is seen that my invention affords acarrier of simple construction for safely transporting heavy circulararticles which otherwise are awkward to maneuver. The carrier alsofunctions as a jig for performing such operations as mounting a grindingwheel stone on -a hub.

While I have shown and described only a single embodiment of myinvention, it is apparent that modifications may arise. Therefore, I donot wish to be limited to the disclosure set forth but only by the scopeof the appended claims.

I claim:

1. A carrier comprising a circular base plate, diametrically opposedarcuate flanges fixed to the circumference of said base plate andprojecting therefrom, the remainder of the circumference of said baseplate between said flanges being unobstructed to enable the base platewhen lying vertically to move into abutting relation with the end faceof a cylindrical article which rests on its circum-ferential face,diametrically opposed pins fixed to the respective flanges and extendingradially therefrom, connectors pivoted to said pins, a yoke, flexiblemeans suspended from said yoke and attached to said connectors fortransporting the carrier, a pair of opposed J-shaped keepers, meanspivotally mounting said keepers on said flanges, and springs actingagainst said keepers and said last named mean-s urging said keeperstoward said base plate, said flanges being adapted to contain portionsof the circumference of an article abutted by said base plate and thussustain the weight of the article, said keepers being adapted to bearagainst the other end face of the article and thus cooperate with saidflanges to prevent the article from accidentally dropping.

2. A carrier comprising an annular base plate, diametrically opposedarcuate flanges fixed to the outer circumference of said base plate andprojecting therefrom, the remainder of the outer circumference of saidbase plate between said flanges being unobstructed to enable the baseplate when lying vertically to move into abutting relation with the endface of a cylindrical article which rests on its circumferential face,diametrically opposed pins fixed to the respective flanges and extendingradially therefrom, connectors removably pivoted to said pins, meansattached to said connectors for suspending and transporting the carrier,a pair of opposed J-shaped keepers, means pivotally mounting saidkeepers on said flanges, and springs acting against said keepers andsaid last named means urging said keepers toward said base plate, saidflanges being adapted to contain portions of the circumference of anarticle abutted by said base plate and thus sustain the weight of thearticle, said keepers being adapted to bear against the other end faceof the article and thus cooperate with said flanges to prevent thearticle from accidentally dropping, said base plate being adapted to lievertically for engaging and trans- -porting the article and to liehorizontally for performing an operation on the article.
